This page is going to describe how to start a new language with lttoolbox. As lttoolbox is not really suited to agglutinative languages, or languages with complex and regular morphophonology (see starting a new language with HFST), we're going to work on one with simpler and less regular morphology.


A morphological transducer in lttoolbox has typically one file, a .dix file. This defines both how morphemes in the language are joined together, morphotactics, and how changes happen when these morphemes are joined together, morphographemics (or morphophonology). For example,

  • Morphotactics: wolf<n><pl> → wolf + s
  • Morphographemics: wolf + s → wolves

These two phenomena are treated in the same file.
